Abstract
A method for improving the corrosion/erosion resistance of Fe-based, Co-based, or Ni-based alloys included in power plants for combustion in a a fluidized bed. The method is characterized in that the surface of the metal alloy is treated in a multi-step combination treatment to provide an adherent and protective surface layer.
